]]>This week, Scientologists around the world are celebrating the birthday of L. Ron Hubbard, born 101 years ago. Here at the Post, we are also marking the date, as a time to revisit our 1964 feature on the author and Scientology founder.

We dusted off this story just last year, when the New Yorker published an extensive investigation and caught our eye with this tidbit: “Hubbard had boasted that Scientology had raised some people’s I.Q. one point for every hour of auditing. ‘Our most spectacular feat was raising a boy from 83 I.Q. to 212,’ he told the Saturday Evening Post, in 1964.”

This article may well be the first in-depth investigation of Scientology, complete with quotes directly from Hubbard himself. And you won’t want to miss the photo of Hubbard’s soup-can E-meter.
